Tesla CEO Elon Musk was on hand recently at a Q&A session in Norway and he offered up some information on current and future Tesla vehicles.

One of the vehicles that Musk talked about was the upcoming Model X. Musk explained that the Model X will have the same wheelbase as the Model S, and that its length will be within 2” of the sedan. The Model X, however, will be quite a bit taller given that it’s a crossover (and to provide additional headroom for the third-row passengers).

Since the Model X will be heavier than the Model S, Tesla figures that the X will have about 10% higher energy consumption.

Musk also stated that the production Model X would definitely retain the "Falcon Doors" for rear seat occupants. The rear doors are hinged in the roof instead B-pillar, which should allow for easier entry/exit in tight parking spaces. All-wheel-drive will be standard on the Model X with a separate electric motor driving the front wheels.

Speaking of AWD, the Model S will receive AWD as an option once the Model X goes into production. Tesla promises that AWD versions of the car will have the same driving range as the current RWD version; something that rarely (if ever) occurs with gasoline- or diesel-powered vehicles.

“Typical experience of AWD is that the efficiency will be worse. We've worked really hard to not have that same effect,” explained Tesla CTO JB Straubel. “We found some clever ways with dual motor AWD, not just mechanical linkage. To make that an efficiency neutral option breakthrough. Flat efficiency tradeoff.”

Software updates coming to the Model S will add a hill-hold function and allow manual selecting of ride height over a wider range of speeds. Feature updates coming down the road will include guidance lines on the backup camera, adaptive cruise control, and Musk also promised that Model S cars coming off the line in the near future would have more comfortable front seats. The new seat can be retrofitted into existing cars.

Another thing I don't understand, why do Teslas have an engine compartment and hood? I mean these is no engine in there, the batteries are under the seat... it's like they want you to think it's an actual car and not a fast golf cart.

Both vehicles are ugly to me, but the SRX is WAY better looking than the CTS Wagon. I'm not the only one who thinks so, since the SRX has been Cadillac's best selling car every years starting in 2010.

All cars benefit from torque vectoring. The high weight and center of gravity means a crossover is in greater need of traction at the wheels than a smaller car. People don't buy a car to inspect its traction (they should, but few people understand it, including you); they buy a car for what it can hold, its looks, its upfront cost and it's cost of ownership (fuel economy, maintenance, etc...)

That Tesla article you provided didn't say anything about the car's performance in snow. It said the car doesn't brake or charge the same due to the cold. In other words, it takes longer to charge, and the car brakes like a regular car without regenerative breaking. Not exactly a crisis, even if it's undesirable.

The four motors... They're smaller than a single, large motor. And there's no drive train (if using wheel hub engines) or a short drive train (if using inboard engines), so the weight would actually be LESS.

The front hood is a trunk, and the car is far more resilient than a golf cart.

My opinion is that the SRX is absolutely disgusting. My opinion is that four motors would weigh a lot more than a driveshaft or just a rear motor. My opinion is that an EV becomes twice as annoying in freezing weather... well that one is actually a fact..
